.To MH when it mrtg concern/ Be it known that l, Jo'nN L. GIVEN, acitizen of the United States, and a resident of Thomplqins Cove, in thec nnty of Rockland and State of New York, have invented. certain new andnselnl improvements in Mal;- ing Concrete lille-ils, ot which thefollowing is a specilieatien.

rlliis invention relates to improvements in making concrete walls; andthe object of my .invention is to provide a nenT and improved means lorsecnrelyl holding the nprights against which the planling rests thatterms the side walls ofthe pocket in which the mixture olE concrete erany other mortar-like suhstencelroin which the Wall to be built can befilled and temps-d, which means are simple in construction, strong anddurable, permit ot' readily erecting and readily detaehing the sideWalls, and do not require the use of e2ipensive braces and struts, andhence donot occupy inn ch space.

In the accompanying drawings, in which like letters of referenceindicate like parts in all the theatres, Figure 1 is an cuter side viewof part of the wooden side Wall for making a concrete Wall. Fig. 2 is avertical transverse sectional View through a concrete Wall partlyiinished and tl ongh the easing and framing vfor the saine.

In making Walls 0i? concrete or of mixture of cement or lime and sand,cinders, broken stones, and the like this mixture, While inoist to agreater or less eltent, is 'filled into a pocket or box the transversedimensions of which are equal to the desired thickness ot the Wall, andin this pocket this mixture is thoroughly tainped, so as toforce out allair and to caisse :in intimate Contact of all the partie es oi themixture. For the purpose of erecting the Wall vertically and keeping itin ro )er sha e the boards or nlanliin which iorin the sides of thispocket are secured to uprights, which in tcrn must be held rinly inposition, so as to prevent their 'spreading under the weight ofthecomposition iilled in between them and under the eilect of the blowsdelivered in talnping.

' Heretotore it lifts been customary to brace uprights hyfn'ieans ofstruts and braces resting af zonta support or seine all et Wliiefn .Y:ferns will? nstihe uprightand against allor'- adjacent 1l'lertieal irequires inueh labor and g ee handling et l ingr hoek-s, belts, ete.
